Cole Porter's Kiss Me, Kate, now in Broadway previews, represents some of the songwriter's best-known and most mainstream work, but the new cabaret show, Confidentially Cole, opening 8 PM Nov. 5 at the Triad in Manhattan, exposes "underground" Porter.

Cole Porter's Kiss Me, Kate, now in Broadway previews, represents some of the songwriter's best-known and most mainstream work, but the new cabaret show, Confidentially Cole, opening 8 PM Nov. 5 at the Triad in Manhattan, exposes "underground" Porter.

Sean Hayden will sing arcane Porter tunes, which carry a theme of forbidden love, longing and obsession, under the direction of Lina Koutrakos. Sally Mayes is production supervisor and Rick Jensen musical directs.

Especially intriguing to Porter fans, two orphaned Porter lyrics whose tunes have been lost over the years will be dressed up with new melodies penned by Steve Ross and Ann Hampton Callaway.

Previews for the act began Oct. 29. Performances continue 10:30 PM Fridays through Dec. 3, with no show Thanksgiving weekend.

Tickets are $20 with a $10 minimum. The Triad is at 158 W. 72nd Street. Call (212) 799-4599. -- By Kenneth Jones
